Functional Description
The following sections provide a functional description of the PCI Lite Core.
PCI-Avalon Bridge Blocks
The PCI-Avalon bridge's blocks manage the connectivity for the following PCI operational modes:
• PCI Target-Only Peripheral
• PCI Master/Target Peripheral
• PCI Host-Bridge Device
Depending on the operational mode, the PCI-Avalon bridge uses some or all of the predefined Avalon-
MM ports. The Generic PCI Avalon Bride Block Diagram shows a generic PCI-Avalon bridge block
diagram, which includes the following blocks:
• Five predefined Avalon-MM ports
• Control registers
• PCI master controller (when applicable)
• PCI target controller
